摘要： A power supply diagnostic circuit includes a switching power supply that generates a voltage for powering a fuel injector. An injector control module selectively applies the voltage to the fuel injector and monitors a resultant electrical current flow through the fuel injector. The switching power supply includes a dual path circuit comprising two inductors, two MOSFETs, and two diodes. The injector control module determines whether one path of the dual path circuit is defective based on the electrical current flow.

摘要： An evaporative emission control system that operates in a running loss mode and an active weathering mode during purge to substantially eliminate running losses during operation of an internal combustion engine. The evaporative emission control system includes a charcoal canister, a canister vent valve, and a purge valve that permits fuel vapors from the canister and engine fuel tank to be purged into the engine's air intake manifold. The running loss mode operates to close the canister vent valve when the gas pressure within the fuel tank increases above a threshold. The vent valve is maintained closed until the fuel tank pressure drops below a lower limit. This prevents running losses by closing the vent when higher pressures are detected that cannot be reduced by purging under the current engine operating conditions. The active weathering mode cycles the canister vent valve open and closed when the volatility of the fuel is determined to be too high for the current ambient temperature. This cycling forces air changes within the fuel tank to accelerate the weathering of the volatile components in the fuel. Fuel volatility is estimated based on tank temperature and fuel vapor concentration. The maximum desired volatility is determined for the ambient temperature and the active weathering mode is begun when the estimated volatility exceeds the maximum desired volatility.

摘要： A fuel control system that estimates the fuel quantity received from purging of an evaporative emission control system and then accounts for the purge fuel in determining the amount of fuel to be injected into a cylinder of an internal combustion engine. Purge fuel quantity is represented by a purge equivalence ratio which is computed based upon an estimate of the hydrocarbon concentration in the purge gas. The hydrocarbon concentration is adaptively learned using an iterative routine that updates the estimate based on the integrated error between the actual and desired air/fuel ratios. Wall wetting and closed loop corrections are applied only to the non-purge fuel portion of the total fuel delivered to the engine cylinder. The closed loop control includes a block learn memory that provides a correction to the factory fuel calibration. The hydrocarbon concentration is updated using the integrated error during purging, whereas the block learn memory is updated using the integrated error during periods when no purging is occurs. The evaporative emission control system includes a solenoid-operated purge valve that is controlled in a manner that provides improved fuel control during transient conditions. The solenoid duty cycle is controlled using a purge factor that operates to reduce the duty cycle when the intake airflow rate drops significantly.
